The reference character 1 indicates a lever and Q-a'hand wheel located within easy reach of the operator and by means of wh ch the" lever 1 may be operated. The lever 1 'is' supporte'dby means of a support 3, the same being shown as arranged ntermediate the "two ends 0fthe lever 1, and said leveris capable of rotary motion about its own axis and capahlealso of a swinging movement Figure lis an isometric with reference to the support 3 above referred to. The support 3 is preferably so designed, and is illustratedas of such form, that the.lever 1 may be swungin any direction from a. given initialpositionwith referswung from side to side with reference .to said support, or may be swung diagonally' the result of which latter motion beingthat the levertakes up a final position to one side of and also above of below its initial position as the dia onal motion may be'conzontal and an up 01', down or a vertical move:

'form' of-a spherical shellas shown in Fig. 4, and a ball 5 is supported within said shell which the lever l 'p'asses as shown, and which construction permits the lever to .be swung in any direction with reference to a given initial position as above pointed out and, the ball not being fast upon the lever, it is obvious that the lever may be rotated ,spective of the position'into which it may have been swung. Obviously the operator may turn the hand wheel 2 to rotate the lever 1, and may lift or depress the wheel bodily, or move it to one side, or, in fact,

swinging motion to the lever 1 as aforesaid. 6 is a spider loosely secured upon the end of the lever 1 so that rotary motion of the Motion of the lever 1 ina vertical or horizontal direction, and consequently in an into the said spider aswill be understood.

7 7 is a member preferably in the form of a flexible cord or cable through which horizontal movements of the lever 1 are transmitted to an element of a machine, an aeroplane in the embodiment of our device illusof the lever 1 to another element of the ma chine with which the device may be used. The elements controlled or adjusted by the members 7, 8 may be the horizontal and vertical rudders of the aeroplane, in which case both such rudders will obviously be imderthe control of a single element, the lever "1.

The :rotaryjmotion "of the leverfl uponl its axis as above explained is utilizedfor adjusting 'or -controllingan-yelement of the ma- 1 chine with nwhiclrourfl device is. used 'other v than the element or elements controlledby swinging movement. imparted to such lever, to which end, in the preferredembodiment k of our device illustrated a-rotary; element 9 isprovided, thefsame-b'eing illustrated as "drum upon whicli a flexibleoordor cable 10 'is wound and the ends "of which extend to theeleinent ofthemachineto be adjusted to thereby hontrol the machine. If used .with anaeroplane, as illustrated, this cord 01" cable will preferably: be connected with the-mechanism for warpmg or twisting the "means-whereby it is prevente 18 tliereby tip the aeroplane upon its ngitlidinal axis. 1 l g i jThe lever- 1, is, in the preferred 'embodiment of ou'rf'device illustrated," 'rov'ided with from longitudinal movement with reference to the sup-' port 3i 'tOwhich end collars 11 are placed upon. the'lever which-collars engage the-ball 5, and {prevent the lever from moving through the ball but do not'interfcre with rotary motion thereofupon its own" axis; Rotary motion of the lever 1 is transmitted to ,the rotary element k0 by means of any suitable mechanism, the preferred mechan- 'ism disclosedroomprising' a rotary connecting member 12 connected with the s end 'of the lever 1 and with the rotary elementlO mechanism in by means of universal joints at 13-,1; and this connecting member ispreferably formed so as to'beofvariable length to compensate for variable distancesbe'tween the end of'the lever 1* and the'rotary element 10 encountered in theoperation ,of; our, controlling its referred, fo'rm. This is best accomplished y .formi-ng the member -12 in two telescoping parts as shown, and

providin two at l I as shown in Fig. 5". Means are provided whereby the lever 1 may belocked in anyposition into which it may have'been moved shown as comprising a screwflSin threaded engagement with the shell of the' support 3, a lever 19 carried by the-lever 1, l

Suoh being the construction" of our devlce' lt will be obvious that swinging move ment 'imparted to the lever 1 about its supa sliding connection between -the port, 3 will be transmitted to an element, 01
